The chassis comes with two radiators. Here you can see the upper radiator, at the rear of the radiators you'll spot four 80mm fans that help scatter heat quicker. Also look at tubing and cable management. That's done right.

In the lower compartment we see the second radiator hidden behind the reservoir. BTW if you are into a  lot of storage .. that's placement for eight HDD's, tooless, and easy to insert. The right drive bay has a 120mm fan behind it cooling them down. The small HDD bay to the left has two 40mm fans blowing over the HDDs from the left.

Fans .. a lot of them. Moving a little upward we see a 120mm fan placed just under the PSU.

If you like to secure devices like your graphics or soundcard conventionally ... your choose. You can use screws yet also this handy retention clip.
